My personal course of study in quantum mechanics hasn't brought me this far and so this question may be incredibly naive, but it has still been troubling me. If the energy of a photon is
E = (hbar)(omega)
and the units of hbar are J*s (obviously), then how can a photon have no mass if a J is defined as 1 kg(m^2)/(s^2)? Is there some kind of limit involved here where the mass approaches 0? I just can't fathom how an object with no mass can even have an energy based on what I know (which is evidently not much).
